I've been contemplating this same scenario right now. I currently shoot an Archery Research AR31. I have always owned PSE products since I started bowhunting. When I purchased the AR it only came with the 65% let off. Their newer models now have 80%. I called their cust. service the other day in an attempt at purchasing the newer cam and module. To my dismay, they told me that they won't just sell me the cam. The rep told me I should consider upgrading to a new bow. I thought about what he said and have considered going out and shooting the newer model Hoyts, Mathews, and Bowtechs. I shoot the AR fine and have been satisfied with it, I was just looking for some relief at full draw. Let me know some opinions.
